mobiai-update

mobiai-update is a skill for Claude Code from ArisGuimera/MobiAI-Core. It costs 55 tokens per session (1,166 once invoked), scanned C, original, MIT.

A skill for updating the MobiAI command-line program and its catalogue of skills using releases published on GitHub. It checks the installed version, downloads the matching release, verifies its SHA-256 checksum, and replaces the installed binary after confirmation.

In plain words
What is it for?
Use it when MobiAI reports that an update is available or when the user explicitly asks for one. It refreshes the skill catalogue and updates the installed program when a newer binary exists.
Why use it?
It avoids manually finding releases, downloading the right file, and replacing the program. The confirmation step prevents an update from happening without the user's approval.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

mobiai-update scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Objetivo

Actualizar el binario mobiai instalado en el sistema del usuario. La vía canónica es mobiai update: desde la v0.2.2 refresca el catálogo de skills y se auto-actualiza el binario (descarga el asset de la plataforma desde GitHub Releases, verifica su checksum SHA256, y reemplaza ~/.mobiai/bin/mobiai con el truco rename-then-write — funciona incluso en Windows con el .exe en uso). El install script queda como fallback para cuando el auto-update falla.

Workflow

1. Confirmá la versión actual

mobiai --version

Anotá la versión (ej: mobiai 0.2.0).

2. Mostrá al usuario qué vas a hacer

Antes de tocar nada, decile al usuario:

"Voy a actualizar MobiAI con mobiai update. Esto refresca el catálogo de skills y, si hay binario nuevo, descarga el release y reemplaza ~/.mobiai/bin/mobiai. ¿Procedo?"

Esperá confirmación. No actualices sin que el usuario diga sí.

3. Corré mobiai update

mobiai update

Refresca el catálogo y, si hay una versión más nueva, se auto-actualiza el binario. Vas a ver algo como:

Skills catalog updated to vX.Y.Z.
N packs available at ...
mobiai binary 0.2.2 → 0.2.3: downloading mobiai-0.2.3-<os>-<arch>...
mobiai binary updated to 0.2.3. Restart your terminal (or re-run mobiai) to use the new version.

Si solo querés refrescar el catálogo sin tocar el binario: mobiai update --skip-binary.

4. Verificá

mobiai --version

Confirmá que la versión cambió. En Windows el .exe viejo queda como mobiai.exe.old hasta el próximo update (que lo limpia en su primer paso); es esperado, no hace falta borrarlo a mano.

5. Fallback: install script

Solo si mobiai update mostró un aviso de que no pudo actualizar el binario (red, permisos, o instalado en una ruta de solo lectura), corré el install script oficial.

Windows (PowerShell):

iwr -useb https://mobiai.dev/install.ps1 | iex

macOS / Linux:

curl -fsSL https://mobiai.dev/install.sh | sh

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
